Rated 5 out of 5 by BigBear Works perfect Everything i expected from a stihl, the precision and reliability is awesome. I have owned every brand and this beats them 10 fold. April 25, 2015

Rated 5 out of 5 by Stretch44 Great product I've had the easy spool on my trimmer for a couple years now and I love it. I'm wondering if people are letting the head ride on the ground constantly which would create friction in the head and in turn melt the line. I just run my trimmer about 1/2 to 3/4 throttle and it cuts everything like butter and the line lasts a lot longer. As far as loading the head, you cut two 3' pieces of line stick them in the holes and twist it untill they are both wound up in the head. I guess that may be pretty difficult for some people to comprehend but whatever. I love it and I will make sure it's on my next trimmer if I ever have to replace this one! March 13, 2015

Rated 1 out of 5 by LineFeeder Very Poor Line Feeding I have been a long time owner of Stihl products. I recently purchased a Kombi Tool with the trimmer and hedge trimmer attachments. I love the hedge trimmer but the line trimmer is terrible. The system wouldn't advance the line as advertised and I had to stop and remove the cap and manually feed the line 6 times while trimming my lawn. I previously had a Stihl trimmer that worked great for years and fed line without fail. This is a serious step backward and I'm planning on returning it to the dealer. July 27, 2014

Rated 4 out of 5 by Rodger69 could be better As with all Stihl products, the multi-task trimmer is a good quality product. It is reliable in every way except a couple of things that are common among string trimmers. The string breaks off inside the housing too often and it is a hassel to constantly be stopping to re-thread the string back through the housing holes. The other part that frustrates me is the method of advancing the string by bouncing it on the ground. It just doesn't work very well. I end up having to bounce several times it seems to get the string to advance. Otherwise I would still rate it better than my old brand of trimmer. June 21, 2014
